Lol, I made a typo in my spoiler with the answer, but I can't edit...it's actually 404.
 Haha..There's actually just a lot of simple little tricks in this one.  The first term is just a geometric series ( 100/(1-1/3) = 150 ). The second is the basic rational limit which comes out to 1 The third is a bit of involved integration, but instead of 1/(x+y)^-k, it simplifies to (x+y)^k to make life easier. Integrate w.r.t. x, leave things in terms of y and k, integrate w.r.t. y, and substitute k=2 to evaluate the limit. Simplifies to 268. The fourth is a differential (which you'd only be able to work out the numerator of if you didn't know that ln(-1) = iπ, from Euler's identity). Apply some chain rule and trigonometry to get -16. The π in numerator and denominator cancel out. Then there's the 1 at the very end to make it 404. "Pick a flower on Earth, and you move the farthest star."
